General Description.

Onreference'to figs. 1 and --1 A represents the square or rectangular frame of a spring bed-bottom arranged to be supported upon-the transverse rails of a bedstead in the usual The conical coiled springs B, for the support of the SIMS 0, rest upon curved cross-pieces F, which extend across the frame A. V

, These springs may be coiled around the slats, as shown at'a, so as to-enable the slats to be longitudinally withdrawn from the same; but I prefer, as fastening devices for the springs, to use rods'a', secured to each s tt directly. above the springs, and passing downwardthrougb the center of the latter, and through. openings-in the cross-pieces F.

These rods slide through the openings in the.

cross-pieces when the slats are lowered or raised, and the springs correspondingly compressed or extended, and, while preventing the lateral displacement of the said springs, enable the same and the slats to be readily detached and removed from the frame by merely raising the said slats, and thus withdrawing the rods. I

:For the purpose of preventing any longitudinal play of the slats, and consequent strain upon the springs B and rods a, I employ what I have termed pull-springs, b, one of whioh'is attached to each end of each slat, and to the adjacent spring B or cross-piccein an inclined position, as best observed in fi 1.'

The action of these springs will be readily understood without'explanation. 7

Instead of adapting the frame A, with its slats and springs, to a bedstead, as above mentioned, it can itself be made to form a bedstead, as shown in the last three figures of the drawing, all that is necessary being to furnish. it with four feet or legs H, and E with ahead-board, M.

The legs H are hinged to the frame A or cross pieces, or to both, at the points 0, and are arranged to be folded up into the frame, so as to occupy but little room when the bed is not in use.

v When extended vertically downward, the said legs areprevented from turning outward by their shoul ders d, which bear. against the side railsof the frame, and they are prevented from turning inward .by diagonal braces K, hinged to the cross-pieoes or frame at the points g, and bent and slotted at their outer ends it, so that they may be readily secured to the legs by T-headed buttons 43 of the latter. fi 4.)

"lhe head-board M is. also arranged to be folded downward upon the end rail of the frame, so that (See it may occupy but little room when not required for use. 1

It consists of a bar, or, (or head-board proper,) whichis connected, to the end rail by a series of double-hinged arms, p and 1), the arms 1) being slotted, and provided with suitable holes, for the admission of thumb-screws or pins q, which are secured to the end rail when the head-board is elerated, as shown In fig. 3, and thus serve to hold the latter rigidly, and prevent the folding of the hinged arms.

g the fran'ic.

' Claims. 1. The springs 12, connected at their nppe'r ends to the ends of the slats, and" at their opposite ends atthe lower ends of the springs B, substantially as described.

2. The combination of the lower slats or supports F, upper slats (3, intermediate coiled springs B, and pins a, when the latter extend through both slats and through the springs,-a-nd can be decached by drawing them through the upper slats, as set forth.

3. The folding head-hoard M, hung to the end rail of the frame, and constructed and arranged to 'he operated substantially in the manner described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
